To all whom it may concern:

Improvements in Sofa-Beds, of which the following is the specification.

My invention relates to improvements in sofa beds and the object of the invention is to devise a bed of this class which is com pact, in which the foot portion of the bed lies within the frame back of the lounge behindthe upholstered back thereof and yet separated therefrom, in which the bed may be unfolded or refolded by a sin le operation with a minimum amount of e ort whereby the lounge back is carried from a position in front of the folded foot portion to a position beneath the unfolded center portion of the bed or the seat portion of the lounge and at the same time so forming the bed that the mattress is independently removable therefrom and separated from the uphol-' stered seat and'upholstered back and it consists essentially of a lounge frame, a bed frameswung within the lounge frame and divided into sections swingably connected together, a seat portion for the lounge secured to the back of the center bed section, a supporting leg for the outer end of such center bed section, -a bracket extending inwardly therefrom, a lounge back swung in proximity to its lower edge upon the bracket, a substantially right angular lever swung on the sides of the lounge frame in proximity to the end of the short arm' and connected to the end of the long arm in proximity to the opposite or upper edge of the lounge back, a resilient connection between the extreme end of the short arm of the lever and the loun e frame whereby the weight of'the bed is li tedduring the upward throw and supported during the downward throw as it is unfolded or refolded as hereinafter more particularly explained by the following specification.

. 1 indicates the lounge frame comprising the end members 2 and 3 and back board 4. The back board 4 is connected to the portions -2 and 3 by brackets 5 and 6. The brackets 6 are permanently secured to the side portions 2 and 3 and are detachably secured to the back board by bolts 6". The brackets 5 are permanently secured to the side portions 2 and 3, the right angular inwardly extending flange bein provided with a vertical slot 5". 5 indicates a stud extending inwardly from each endv of the back board 4 and provided with a suitable head so as to engage with the vertical slot 5* when slid vertically thereinto. By this means the side portions'2 and 3 are connected together by the back board 4. 7 indicates 'a bracket which extends inwardly from each of the side portions 2 and 3 in proximity to the back thereof, such bracket being provided with a notch 7 for a purpose which will hereinafter appear.

8 indicates'a bracket (see Fig. 5). The brackets 8 extend from each of the side portions 2 and 3 in proximity to the front thereof and are provided with a vertical notch 8 for a purpose which will hereinafter ap pear. 9 indicate rectangular frames located at the inside of each of the side portions 2 and 3 and comprising the vertical angle bars 9' and 9 connected together at the bottom by the angle bar 9*; having the horizontal flange 9* thereof turned outwardly. 9 indicates a of the vertical bar- 9 Thev outwardly extendingflange 9 of the angle bar 9 restsin the notch 7 of the bracket 7. 10 indicates a stud extending inwardly from the outwardly extending flange of the bar 9 When the flange 9 is inserted in the notch 7 the stud 10 is slid vertically down into the vertical notch 8 of the bracket 8. Ihe

frames 9 located at each end of the lounge are supported upon the portions 2 and 3 in to which are pivoted the si e bars 14 and 16* the end of the- -sidebar14 being also pro vided with a notch 14. as shown in this figure. The end of the side bar 16 adjacent the side bar 15* is provided with an open ended. slot 16 15 is a bar secured to the side bar 15 in alinement with the slot 16 This construction allows of the side 16. being swung freely forward from the position shown in Fig. 6.' When the side bar 16* is swung in the opposite-direction it engages the bar 15 to carry the bars 15 and 14 upward.

I merely describe this constructlon in order to make the operation of my device clear but do not lay claim to it as new as it is the common construction usually employed in this class of bed.

The bed frame 13 is pivoted at 13 to a bracket 9. secured to each bar 9 18 indicates a bracket extending upwardly from each bar portion 14*. 19 indicates a link connecting the u perend of the bracket 18 with the bar 9 o the frame 9. 20 indicates the seat portion of the lounge which is of upholstered construction and supported upon the frame 21 connected to the side bar 16 of the bed frame. 22 indicates alongitudinal bar extending between the portions 2 and 3 and suitably connected thereto. 23 indicates a flap of flexible material extending from the upholstered seat portion 20 to the longitudinal bar 22 to which it is secured. 24 indicates a leg depending from each of the side bar portions 16 of'the bed frame 13 in proximity to the outer end of such side bar portions. 25 indicates a bracket extend mg inwardly. from each of the legs 24. 26 indicates the upholstered back body of the lounge provided with" end bars 27 pivotally secured at 28 to the brackets 25. 29 indicate right angular levers comprising the short arm 29 and the long arm 30. The short arm 29 of each lever 29 is pivoted intermediately of its length at 31 to the top bar 9 of each side frame 9. The end of the long arm 30 of the right angular lever 29 is pivotally connected at 32 to the bar 27 33 indicates a bar secured to each of the bottom amaze to the leg 24. 36 indicates a bar forming an extension to each side bar 16 of the bed-- frame. The side bars of the foot section 17 are pivotally secured at 17?. between the bar portion 35 and the bar portion 36. 37 indicates a supporting leg for the 'outerjend of the foot section 17 of the bed. lhe leg 37 is pivotally connected to the side bars of such foot portion at 37*. 38 indicates a link piv-,

otally connected at one end to the supporting leg 37 intermediately of its length and at the opposite end to the extremeend of the bar 36. 39 indicates a strip which is securedto the outer end of the foot section 17 and designed to form a top or finish'for the lounge back when the bed is folded against the back board as shown in Fig. 2 of the drawings.

40 indicates the ordinary mattress which is supported in a suitable. manner upon the bed frame 13 so as to fold with the bed frame when carried from a horizontal to the folded position. "41 is a vertical'angle bar secured to thebars 9 and 9 and spaced apart'from the bar 9 to form a vertical guideway 42. 43 is a slide bar located in the guideway. 44 and 45 are plates riveted to'the bar 43 at each sideand forming a vertical edge groove into which the opposing edges of the angle bars 9 and 41 extend; lhe lower end of I the bar 43 is out-turned and the upper end of the out-turned flange of the angle bar 41 I is desired to unfold the bed from the position shown in Fig. 2 to the position shown in Fig. 4 all that it is' necessary to do is to grasp the portion 39 connected to the foot portion 17 of the bed and draw it outwardly and upwardly in an arc-shape direction. This movement is aided by the tension of' the spring 46 drawing upon the lower end of the slide bar 43- exerting. an upward pressure on the upwardly movlng portion of the bed. Simultaneously with this upward movement of the foot portion of the bed the upper edge of the back portion of the lounge 1s carried in a circular path by the long arm of the lever 29- around its center of swing formed at 28 thereby carrying it from the position shown in Fig. 2 to the position shown in Fig. 3 against the upholstered seat portion 20 of the lounge. Such back porthis operation takes place, the tension of the spring shown in the position in Fig. 4

' tending to counterbalance the weight of the foot portion of the bed as it is removed to the highest position and as it drops to the closed position against the back board 4 of the'lounge frame the roller 47 engages the slide bar 43 the weight then being carried by the spring 46.

From this descriptionit will be seen that I have devised a sofa bed in which a minimum amount of exertion is necessary to open the bed to an unfolded position or refold it to a closed position and at the same time providing a bed in which the mattress is entirely separate from the upholstered portions of the lounge and, therefore, independently removable therefrom and in which the back of the lounge seat is carried with the bed from its normal position, when forming the back of the lounge, to a position beneath the seat portion of the lounge when the bed is in its unfolded position.

What I claim as my invention is.
